What happened on this date in Mormon History - several curious snippets every day

165 years ago today - Sep 21, 1851

[Hosea Stout]
I learned to day that Howard Egan, who has returned forom the gold mines lately, and upon learning that his wife had been seduced or in other word had had a child willingly by James M. Monroe during his absence. Said Monroe had also gone to the States for goods for Reese and was now on his return here, whereupon Egan went and met him near Cach Cave and after talking the matter over sometime Egan drew a pistol and shot him dead which makes the second man who has been deliberately shot dead for the same offence in less than one year in the Territory.
